#### Tools Required

• | J 8059 Snap Ring Pliers

• | J 35566 Earless Seal Clamp Tool

• | J 35910 Seal Clamp Tool

1. Install the new small seal retaining clamp (2) on the neck of the tripot seal (1).
2. Do not crimp the small seal retaining clamp.
3. Clean the halfshaft bar. Use a wire brush to remove any rust in the seal mounting area (grooves).
4. Slide the tripot seal (7) onto the halfshaft bar.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

5. Position the neck of the tripot seal in the seal groove (3) on the halfshaft bar.
6. Crimp the seal retaining clamp (6) using J 35910 , a breaker bar (9) and a torque wrench (8).

Tighten
Tighten the seal retaining clamp to 136 N·m (100 lb ft).

7. Check the gap dimension. Continue tightening until the gap dimension is reached.
8. Install the spacer ring (2) on the halfshaft bar (1) and beyond the second groove.
9. Slide the tripot joint spider assembly (3) toward the spacer ring as far as it will go on the halfshaft bar.

Important: Ensure that the counterbored face of the tripot joint spider (4) faces end of the halfshaft bar.

10. Install the halfshaft bar retaining ring (2) in the groove of the halfshaft bar using J 8059 .
11. Slide the tripot joint spider assembly (3) towards the end of the halfshaft bar.
12. Reseat the spacer ring in the groove on the halfshaft bar.
13. Place approximately half of the grease from the service kit in the halfshaft inboard seal. Use the remainder of the grease to repack the housing. Ensure the bushing is flush with the face of the housing.
14. Install the trilobal tripot bushing to housing.
15. Position the larger new clamp (3) on the halfshaft inboard seal (2).
16. Slide the housing (4) over the tripot joint spider assembly on the halfshaft bar (1).
17. Slide the large diameter of the halfshaft inboard seal (2), with the larger clamp (3) in place, over the outside of the trilobal tripot bushing.
18. Locate the lip of the seal in the groove.
19. Position the joint assembly at the proper vehicle dimension.

Important: The halfshaft inboard seal (3) must not be dimpled, stretched out or out of shape in any way. If the halfshaft inboard seal (3) is not shaped correctly, carefully insert a thin, flat, blunt tool (no sharp edges) between the large seal opening and the trilobal tripot bushing to equalize the pressure. Shape the halfshaft inboard seal (3) properly by hand. Remove the thin, flat, blunt tool.

Important: Align the following items while latching:

• | The halfshaft inboard seal (3)

• | The housing (1)

• | The large clamp (2)

20. Latch the seal retaining clamp (2) using J 35566 .
